Answer 1

Respuesta:

1) 100 + 200 – 170 – 40 = (100 + 200) – (170 + 40) = 300 – 210 = 90

    R/ Le queda $90

2)

a) 18 – 9 + 7 + 9 – 5 + 6 = (18 + 7 + 9 + 6) – (9 + 5) = 40 – 14 = 26

b) 50 – 5 – 6 + 4 + 8 + 1 – 5 = (50 + 4 + 8 + 1) – (5 + 6 + 5) = 63 – 16 = 47

c) 3 – 6 + 8 + 15 – 6 + 3 + 6 = (3 + 8 + 15 + 3 + 6) – (6 + 6) = 35 – 12 = 23

d) 13 – 10 + 3 – 14 – 1 + 13 + 16 = (13 + 3 + 13 + 16) – (10 + 14 + 1) = 45 – 25 = 20

e) 54 + 6 – 30 + 17 + 3 – 4 + 35 – 24 = (54 + 6 + 17 + 4 + 35) – (30 + 4 + 24) = 115 – 58 = 57
